Inbound buses and light rail vehicles will be detoured over Arlington Avenue; outbound light rail vehicles will continue to use the Mt. Washington Transit Tunnel. Outbound buses will use the Wabash Tunnel.

Additionally, the Wabash Tunnel will only operate in the outbound direction throughout the duration of the project. Noncommercial vehicles will continue to be permitted to use it.

Port Authority will operate a rail shuttle between Station Square Station and Steel Plaza Station throughout the project. The shuttle will also serve First Avenue Station.

All riders should allow extra travel time. Delays of up to 20 minutes are expected during peak travel times.

The work includes replacing 400 feet of light rail tracks in both the inbound and outbound directions. The tracks have reached the end of their useful life. The cost of the work was included as part of the $8.4 million Broadway Avenue reconstruction project performed by Michael Facchiano Contracting.

The announcement of this work was delayed because of the uncertainty around the reopening of the Liberty Bridge.
